oil in water

[Aweik02]

well the title says it all. How long can I run it like this with out serious consequence? I'm not sure when I'll be able tear into the truck either... What should I do?

[dieselnomad]

do you mean like oil in the radiator or the overflow jug?

If so, you'll want to deal with that pretty quickly, IMHO. How's the truck drive otherwise?

[95Cummins]

It probably just pushes in there at high boost, when the head is pushed farthest from the block, that would be my guess.

[PToombs]

You're going to have to fix it or stop driving it. If oil is going into the water, the 2 will react and the whole block can fill up with thick slime, and it's a son-ofa-gun to get out. The other thing is, if A/F is getting into the oil, it will take out the bearings in a quickness.

water in oil will spin a bearing, and literally self distruct a motor within a very short time especially when cold

Well, Aaron said Oil in Water, not water in oil.

Hey Aaron, what's it look like in the overflow jug?

And, to address what Pete and Kyle are bringing up, why not run an oil analysis? Go to : http://www.blackstone-labs.com/ and order an oil analysis kit. Maybe you can have it overnight to you so you can run a test?

In the meantime, I would be really hesitant about driving it- and if you do, be hyper sensitive to how it behaves and if the leak gets worse, or theres more oil in the water, etc. It won't get better over time and will get worse on the engine.

I haven't had a blown HG <KNOCK ON WOOD> but I thought I did last winter and ended up doing a lot of reading on it-- Last weekend I did have a scare though- after an unusual hard run the next AM I found a finger nail speck of oil in the radiator :eek: The overflow jug was near empty (I've done a lot to the truck over the past two months, this could be an oversight). So, I topped off the overflow jug with good clean A/F and after more than a few heat and cool cycles all looks OK.

If you look on BlackStone's site, you might also be able to pull an A/F test. Good luck, and becareful if you choose to drive the truck.

There's small amount of sludge in the overflow and some tiny tiny bubbles on the dip stick. I just drove 9 hrs to Ohio Thursday too. Fck. Hey im gonnna be on pinks in six minutes. I'll be back.

[Jim]

Are ya certain its oil? Could just be slimey stuff from not servicing the coolant system, or mixing extended life coolant with regular glycol? Have you or the prev. owner ever used stop leak?

As far as bubbles on the dipstick, is it green? Usually AF will sink to the bottom of the oil pan and when you drain it out it will come out first.
The bubbles may just be from the oil foaming a little?

Standing by.

[Aweik02]

Aright, so I guess the preveiw channel is alittle backwards I think I'll be on pinks at 2230 not 2100 Maybe the slime isn't oil... Regular BST pressure is 42lbs, isnt that kind of the brink? There's no visible coolant around the head/block, only at the thermostat housing... In gonna check the oil again tommorow. I wish I could upload some Pics. I'm gonna look in the yellow pages tonight for a close diesel shop and see if they can do a quick oil analysis... I guess for now I'll just baby it? I don't wanna drive it if I gotta worry about spun bearings, sucks being 10hrs from home too. Just my luck! I've never serviced the coolant system, and I doubt the first owner did either since the truck was one owner 80K when I bought it. I did add AF before I left with no regard to type. Would there be traces of oil in the Rad if it was in the O/F?

[Jim]

most big truck shops like cat, international, cummins, etc will have oil analysis capabilities. Do you have a milky film on the dipstick?

[Jim]

Do you have a milky film on the dipstick?
Man im gonna take some hits for that one!:smilielol:

[Aweik02]

no milky film here you:ptown: bastage. Just minute bubbles. Not big enough to notice color. I'm gonna look again tommorow. I hope its nothing, this isnt the time for my truck to be on the limp...

[Warpig]

Quit being paranoid :poke:

[Aweik02]

your wright... Its prolly nothing but, better safe than sorry. Gonna call around right now about an analysis.

[PToombs]

After the truck sits overnite, crack the oil drain loose a turn or 2. If there is A/F in the oil, it will seep around the threads on the plug.

[turbo246]

oil is lighter than water, water sinks change the oil and see what comes out as soon as you pull the plug...? just a thought

[PToombs]

Why waste the oil if it's ok? Check it like I said and you'll know. :HoleShotHolset:

x2:exactly:

[Aweik02]

I'm gonna go try that right now. Truck hasn't been run since 6 lastnight. Thanks for the help.

[Aweik02]

No AF at the drain plug... And nothin abnormal on the dipstick. What would cause sludge in the overflow bottle?

[sooter]

are there any bubbles in the overflow tank while running?

42psi is pushing it...especially on the ETH's. i'm not going over 35psi now until i have it redone with o rings and studs (had to redo stock myself this winter...a lot of work, but not difficult).

[PToombs]

Open the radiator cap, start the truck. If you see bubbles or the A/F starts to push out you have a problem. Most likely a head gasket. If it's the oil cooler, you should only get oil, no bubbles, no immediate overflow.
I have only seen 1 or 2 coolers go bad on these engines, and I work on them for a living.
If the cooler popped, the oil level will go down pretty quick.
I'm wondering if it's what Jim said, mixed anti-freezes, or just a dirty bottle.

Did you ever see oil in the radiator? I just went back thru the posts, and you didn't say! If not, I bet it's just what you added!

[Warpig]

Probably old fluid, kinda like pond scum.

[Aweik02]

Well it looks like I may have cried wolf. I found a truck shop about half hour from where I am and will have an oil analysis Monday. Thanks for the help, I believe fire rings and studs are in order once my tax return shows up.

[matt95]

How bout some pics of your truck with those wheels on it!!!!

[Aweik02]

They didnt show up at my house until the day after I left. I'll be home in June and I'll mountem up then. I've got black splined lug nuts to match. Might have the centers pc'd or painted black.
